AC Input Wiring – Connecting the Pendant to the 115VIF-3 Interface Board

Connect the pendant 115 VAC input wiring to the terminals marked AC1 through AC5 on the 115VIF-3, with

NEU (neutral of the pendant control signals) as their common terminal. AC1 thru AC5 are connected to the

HOT side of the pendant control signals, coming from the pendant’s pushbutton contacts. The board’s AC input

terminal functions are as follows:

Note 1: Inputs AC1 and AC2 functions are symmetrical with respect to direction in traverse applications. In hoist applications, however, AC1 must be

used for UP and AC2 must be used for DOWN.

Note 2: AC4 and AC5 inputs are intended to be used with over-travel limit sensors. These are secondary safeties, over and above N.C. limit switches

that would be wired in series with the AC1 and AC2 pendant inputs. They are “fail-safe” inputs, for use with N.C. type sensors. In this way, a

cut wire will have the same effect (inhibited of motion) as a sensor being triggered.

Note 3: AC4 may also be used for 3-Step Hoist Control. Refer to page 11.

Important: If you will not use the

AC4 or AC5 for end-of-travel safety

inputs, then both these inputs must

be jumpered to the pendant HOT

supply, otherwise motor rotation will

be prevented. When end of travel

limit switches ARE used, they should

be wired in place of these jumpers.

Connecting the Board to the Inverter

The method of connection of the 115VIF to the inverter depends on the inverter model. Refer to the appropriate

section below for the inverter model you have.

SJ200

The eight “fingers” on the 115VIF-3, as shown at the bottom of Figure 2-1, are designed to mate directly with

the input terminal strip of the SJ200 series inverter. It is best to remove the terminal strip from the inverter first.

Then loosen all the terminals to allow the fingers to be easily inserted. The correct orientation for the board is

with the integrated circuits facing upward, and the AC input terminals facing downward toward the inverter.

Insert the eight fingers until you feel them hit that back of the terminal wiring chambers. Do not try to force

them – they should enter easily. Tighten all eight terminals securely. Be careful to not over-tighten.

Connect the AC signal wires from the pendant controls to the terminal as shown in the table on page 6. After

carefully tightening all terminals, reinstall the terminal strip with attached board into the inverter mating

connector, and route pendant AC wiring carefully out the bottom of the inverter.

Figure 2-3 shows the correctly installed 115VIF-3. Make sure the SR/SK DIP switch is in the default “SR”

position. Replace the inverter lower terminal cover, and energize the inverter and external control circuits for

configuration and testing.

When installed in an SJ700 inverter, the 115VIF-3 must be mounted behind the inverter top front cover in the

area where option boards are installed, as shown in Figure 2-4. Install the board in the lower position (c

terminal strip) as shown. This will leave the upper option slot free should a SJ-FB feedback board (for

closed-loop operation), or other option board be required. The optional 115VIF-KIT mounting kit is required

when mounting the interface board in these inverter series. The kit includes a pigtail cable and a M3 x 8mm

mounting screw. Plug the pigtail connector into the mating OUTPUTS2 connector on the board. Align the

Chapter 3 – Configuring the Inverter

The configuration of inverter parameters will depend on the specific functionality and performance required for

your application. The basic functionality of the board is designed to interface with a two pushbutton,

two-position (two-speed) momentary contact type pendant commonly used for crane and hoist applications. This

is the basis for the descriptions of the functions of the board presented in this manual. The setup in the table

below will result in infinitely variable speed between the programmed MIN and MAX speeds. The defined

functions of the pushbuttons are as follows:

DOWN

UP, first detent: UP – accelerate to minimum speed

UP, second detent: UP – increase speed while held, up to MAX speed (or go to second speed, see page 10)

DOWN, first detent: DOWN – accelerate to minimum speed (RESET fault when inverter is

STOPPED and in a fault state)

DOWN, second detent: DOWN – increase speed, up to MAX speed (or go to second speed, see page 10)

Pushing either the UP or DOWN pushbutton to the first position causes the inverter to go to the minimum

configured speed in that direction. Pushing that button further to its second position will cause speed to increase

in that direction. Releasing back to first position will hold that last speed. Releasing the pushbutton all the way

will cause the inverter to come to a stop. If that button is re-pressed to the first position before stop is reached,

that speed will be maintained.

In order to achieve this basic functionality, certain parameters must be set differently from factory default

values, as described in the following table.

Other Required Settings

The following were previously noted in the Installation and Wiring chapter, but are important and bear

repeating. Make sure the following steps were performed.

SJ200

The SR/SK DIP switch next to the input terminal strip must be in the default “SR” position for proper operation

of the 115VIF-3 interface board. Verify that it is in the correct position. Confirm the correct setting of B091 for

load-brake vs. non-load-brake applications.

SJ700

Confirm that the silver source/sink jumper bar is between PLC and CM1, as explained in Chapter 2. Confirm the

correct setting of B091 for load-brake vs. non-load-brake applications.

Alternative Set Ups

Two-Speed Operation

The inverter can easily be configured for two-speed operation rather than infinitely variable speed operation by

using the following parameter settings in lieu of or in addition to those in the table above:

C003

Terminal 3

02 [CF1] function – multi-speed select bit 1

C004

Terminal 4

Function

255 [no] No function

This set-up is applicable to pendant stations with two-position pushbuttons, and can be applied to hoist

and/or traverse axes. With the above settings, at the first pushbutton position, the inverter will ramp to

MIN speed and hold. On depressing the button to the second pushbutton position, the inverter will

accelerate to the A021 speed and hold. Releasing the pushbutton back to the first position will cause

the inverter to decelerate back to the MIN speed and hold. Releasing the pushbutton will cause the

inverter to come to a stop.

Three-Step Hoist Control

Some pendant stations utilize 3-position pushbuttons for the hoist control. This is what is traditionally called

“three-step control.” This is simple to implement with the 115VIF-3 and inverter. No programming changes are

required in the inverter. The jumper from AC4 to HOT that would be used in normal 2-step operation is not

needed in this case. The output wire from the pushbutton second contact is wired to AC4 instead. The increase

speed input signal will be taken from the third pushbutton contact for this setup, instead of the second as in

2-step control. To implement this function, refer to Figure 3-1 and the following table which summarizes the

connections that are used:

Chapter 4 – Operation

Normal Operation

Once the inverter parameters are set as described in Chapter 3, you are ready to verify proper operation. It is

recommended to first test the system with the motor mechanically disconnected from the crane or hoist, to

ensure that any unexpected behavior will not damage the equipment or risk injury.

Energize the inverter and the pendant or other external control circuit power supplies, and press the pushbutton

connected to input terminal AC1. This is the UP hoist or FORWARD/LEFT traverse input. Observe motor

rotation. If direction is NOT correct, remove power from the inverter and wait 10 minutes for the capacitors to

discharge. Then interchange any two motor leads. Restore power and repeat the initial test. Direction should

now be correct.

With the AC1 pushbutton pressed to the first detent, the motor will accelerate in the forward direction,

(corresponding to UP motion for the hoist), to the frequency set in A062 (MIN speed), and remain at that speed,

unless:

• The pushbutton is released, in which case the motor will come to a stop, OR

• Ramp to a higher speed, while pushbutton is pushed to the second detent (AC3). If AC1 is maintained,

and AC3 is subsequently released, the speed attained at that time will be maintained.

• Releasing AC1 at this point will cause the motor speed to ramp down.

• If AC1 remains off long enough, the motor will come to a stop.

• If AC1 is re-activated at any speed above the MIN speed, then that speed will be maintained for the

duration. If AC1 is reactivated at a speed below the MIN speed, the motor will accelerate to MIN speed

and maintain that speed until one of the above events occurs.

The function of AC2 pushbutton is the same as the AC1 pushbutton, with the exception that rotation direction is

reversed (corresponding to DOWN operation for a hoist).

In addition to its normal function, the AC2 (DOWN) pushbutton input doubles as the FAULT RESET if the

inverter should enter an alarm (trip) condition for any reason. This eliminates the need to access the inverter

keypad itself to clear a fault.

Troubleshooting

Symptom Remedy

Inverter will not accelerate beyond minimum speed Input AC4 is not jumpered to HOT

Inverter will only turn the motor in one direction Input AC5 is not jumpered to HOT

Note: For other troubleshooting tips, refer to Chapter 6 of the pertinent inverter Instruction Manual

Electrical Specifications

The board is internally powered from the inverter’s internal 24 Vdc power supply, drawing approximately 21

mA. The AC inputs are optically isolated, and draw approximately 2 mA each. The outputs to the inverter have a

100 mA maximum capacity.
